KEYBOARD TAPE-PERFORATOR.

1 ,os5,9s5.

To all whom it may concern Be it known that I, Eowano E. KLEIN- HUHMIDT,a citizen of the United States, residing at New York city, borough ofManhattan, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Keyboard'lape-Perforators, of which the following is a specification.

My invention relates to an apparatus for perforating tape by means ofpunches oper ated in combinations or groups, and controlled by selectorkeys, one for each combination or group, the perforated tape beingadapted for use in a VVheatstone or any other telegraph transmitter.

In my application, Serial No. 549,492, tiled Marclrlfith, 1910, I havedescribed an apparatus comprising a key board selective mechanismadapted to set groups of punch controllers, of various arrangements andnumbers, corresponding to or representing the letters or other symbolson the key board; and means for actuating the controllers, and throughthem the punches, .t'or perforating a strip of paper to produce theelectrical signal equivalents of the key board characters.

The present invention embodies substantially the same principle ofoperation of the punches and has for its object to simplify and improvethe construction, of the selective mechanism, punch controllers, punchesand the variable feed mechanism.

My invention will be understood from the following description taken inconnection with the accompanying drawings in which- .Figure 1 is a planview of the perforator with the rising broken away; Fig. 2, a sideelevation; Fig. 3, a transverse section through the key board on theplane of the.

Serial No. 685.013.

Similar reference numerals indicate similar parts in the several views'The perforating apparatus herein described, comprises (1) a key boardselector mechanisr-t; (2) perforating mechanism; (3) a variable feedmechanism; and t) a paper control. I will describe these several partsin the order above given.

The key board selector rhechanism.-The

purpose of this part of iny apparatus is to po ition what I ,term' punchcontrollers, thesecontro'llers being adapted to be moved into the pathofa platen, or a punch head, to engage the corresponding punch to perforate the tape. it comprises a bank of key bars 1, the keys of whichare provided with the charactersof a universal key board, and the latterincludes an additional bar for extra spacing between messages. All ofthe ltey bars are fulcrumed near their inner ends on a fixed transversebar 2. Arranged longitudinally of and beneath the key bars, are notchedbars 3 fulcrumed near their inner ends on a transverse bar 4, andretained in their normal positions. in contact with the under edges ofthe corresponding key bars by springs 5 fixed at one end to the base ofthe frame. Secured upon opposite sides of each key bar are small guideplates ti, and between said plates the notched bars 3 rest to preventsidewise movement, each bar 3 having a short projecting-section on itsupper edge to pass between the guide plates 6, as shown in F igs. 2 and3. A transversely extending stop 7 limits the downward movement of bars3 when depressed by the key bars, and a stop 7"limits the upwardmovement of the key bars.

The purpose of providing a notched sclector bar instead of notching theunderside of the key bar, as in my former application, is to provide foran equal extent of movement of the outer or key ends of the key bars.The key bars 1 have a common fulcrum 2, as above stated, and the guideplates 6 are placed on the key bars at varying d1s-' notched bars and ofthe key bars, there being one of said T-hars for each punch controller,and a universal bar, shown in Fig.

3, which is adapted to be depressed when I any one of the key bars isdepressed. The T-bars are supported by parallel links 9 pivoted to thele s of said bars, the other ends of said links being pivoted on abracket 10 secured in the frame.

8 is notched to receive a connecting bar 11, only the first and last ofsaid legs and bars and 5, these hats 11 alternate in length tofacilitate assembling, and are fulcrumed able link connection, as shownfor the purpose of properly positioning the upper ends of thecontrollers relatively to the punches.

These punch controllers have a vertical' movement through openings in apunch head 16 which will now be described.

The perforating mechanism.The particular perforatingmechanism shown byme, for purposes of illustration, is intended to perforate a tape to beused in a VVheatstone transmitter. As shown, the perforator com- 5prises two rows of punches 17 and 18 there "being shown in Fig. 3. Asshown in Figs. 2

near their inner ends either on the same bar 4 upon which the notched.bars 3 are fulcrumed, or upon another bar'in proximity to the bar so asto insure a substantially equal movement of the punch controllers.Slotted plates 13 (Fig. 3) receive the ends of the T-bars 8 and guidethem in their vertical movements when depressed. by the notched selectorbars 3, and when raised by the springs 12 attached to them be 0nd theconnectin bar 4. By reason 0 links the T-bars 11 will always move in avertical ath by whichever notched bar 3 a given 'F-bar may be depressed,that is, there will be no tilting of a depressed T-bar when moved by theextreme notched bars.

By having a common fulcrum bar 4 for the selector bars 3 and theconnecting bars :11, or by having the fulcrums. in close proximity toeach other,' a substantially equal extent of movement of the outer endsof the connecting bars 11 is insured, whether 5 a given bar 11 isdepressed by a T-bar 8 That near to or removed from the fulcrum. is, byreference to Figs. 3 and 4 it will be seen that each Thar 8 is adaptedto be de- 3 and that when a given T-bar is depressed fulcrum 4 theextent of movement of'the short arms of the bars 11 will be equalwhether that bar be connected to the nearest or to the farthest T-bar.This equal ing bars 11 insures an equal movement of all of the punchcontrollers.

The ultimate work performed by the selector mechanism is to position thepunch controllers 1 and .15 connected to the inner ends of the connectinbars 11, as shown in F ig. 5, and arranged in two rows, as shown theparallel being ten ineach row, it being understood One edge of thevertical legs of the T-bars of course that there maybe as many punchesas desired according to the code. Between the punches 17 and 18 is athird row 19 for punching a center row 01 perforations adapted to beengaged by the teeth of a feed wheel, hereafter described. A bracket 20,secured to the main frame, is provided with guide holes for thereception of the punches which slide freely therein. The punch head 16is slidably supported in the gibs21 and is normally held in itsretracted position, shown in Fig. 5, by a spring 22, being held againststops 24 on the ends of the gibs.

A die-plate 23, supported on the bracket 20, is provided with holesthrough which the punches pass after perforating the tape, the bracket20 being recessed to provide a space for the passage of the tape 24. Thenormal position of the punch controllersand of the punches is shown inFig. 5. When a key is depressed, a group of controllers is raisedcorresponding in number and arrangement to the code symbol of the keystruck, so that their upper ends will contact with the punches. when thepunch head is brought forward.

To move the punch head forward I provide a solenoid 25 (Fig. 6) the coreof which has connected to it one arm of a bell crank lever 26 pivoted onthe frame, The

other arm of said lever is connected to the d b H f th be} d l t b mainoperating lever 27, the latter being presse y a o e no 1e so ec or ars jpivoted on th frame and held in its rei tracted position by a spring 28,(Fig. 7).

ihead 16 (Fig. 5).

cluded in a circuit having a normally open Secured to lever 27 is a stud29 which passes through an elongated slot 30 in the punch The solenoid25 is incontact 31. The lower member of this coni tact is connected to,but insulated from, a movement of the short arms of the connectbar 32,similar to the bars 11, and controlled by a universal T-bar 8 (Figs. 3and 4), so that when bar 32 is depressed the lower contact will beraised and the circuit closed,- energizing solenoid 25. This occurs whenany one of the key bars is depressed. The movement of the solenoid corerocks lever 26 and the resulting forward movement of the punch head 16,through lever 27 and stud 29,

forces those punch controllers 14 and 15,

which have been raised. against the ends of the corresponding punches1'7 and 18 to perforate the tape, there being as many punches operatedas there are punch controllers raised. The punches pass through thepaper and into the holes in ie die-plate 23. When the depressed key isreleased, contact "31 is opened-and solcnoid deenergized. Spring spring28 will restore the main depressed key is-releascd it is restored to its1 normal position by a spring 5 to the notched selector bar .5 depressedby the key bar; and the T-hars 8 which were depressed are restored totheir normal position by the springs 12 acting through the correspondingconnecting bars 11. movement of the connecting bars 11 will restore theraised punch controllers l4 and '15 to tlieirnormal position.

In addition to the punches 17 and 18, which make the characterperforations, an additional row of punches 1.) is located mid waybetween the rows of punches 17 and 18. The punch head 16 is providedwith a block 33 which impinges against the punches 19 upon everyforwardmovement The 1 connected a link 42. and lever 41 has pivotedthereto, a link- L2), the latter having connected to it a pawl 4+pivoted on an arm 4:5 which is mounted on the stud of feed wheel 46.Pawl --l-l is in the form of a bell crank, and has an extended arm Hhaving its end turned down through a slot in arm 45. A spring H engagesthe turned down end of arm H so as to normally hold the toe of pawl iiin cngag'cment with the teeth of wheel 5L7. When the pawl is'positionedfor operat ingwheel 47, the turned down end of arm 44 strikes the rearwall of the slot in arm 45 and prevents the pawl being thrown too faraway from wheel d7. The feed wheel isprovided with teeth on itsperiphery which engage the center row of pcrfora tions on the tape tofeed the latter forward g an amount determined by the throw of pawl ofthe'punch head for perforating a central row of holes adapted to engagea feed wheel, as will be presently described.

To retract the punches after they have been moved forward to perforatethe tape I provide a comb 34, secured to the punch head. As shown inFig. 5 each. punch has fixed thereto a collar 35 which, when the punchesare in their retracted position, rest against a ,stop 36. \Vhen thepunches are advanced the comb 3+ is advanced. and when the punch head isretracted, the comb M -is retracted and carries-with it those puncheswhich have been-advanced until the latter are restored to their normalpo-.

sition with their collars hearing against the stop-36.

T/w'curiublc feed r/wc/umism. -To adapt my apparatus for codes requiringvarying numbers of perforations for the key board characters it isnecessary 'that a variable feed be provided. For that purpose 1connect-with the main operating lever 27, a feed operating lever 34'pivoted on a stud 37'. the

connection being made by a pin 38 on lever 27 engaging a slot 39 in thelever 37, as shown in Fig. 7. The parts are so related to each otherthat the pin 55 will engage therear wall of slot 39 when lever 27 is retracted, and after the punch head 16 has been retracted sufficiently towitl'idrnw the punches from the perforations in the tape, tofeed thetape. At its free end the lever 37 has pivoted thereto. a floating lever40. The lever 40 is connected to a lever 41 by 14. The latter engages aratchet wheel 47 fast to the feed wheel, and said wheel 17 is advancedon the return movement of the pawl, theextent of such movement beingsufiicientto feed the tape an amount equal to the length ofthe lastgroup of perform tions, varying as such lengths vary, and an additionalamount to space the groups. This effected as follows: \Vhen lever 37 ismoved forward, lever 40 is also moved for\ 'ard with its fulcrum on thepivotal connection with linl; at d the upper end strikes the last one orthe punch controllers of the group raised by the selector mechanism.

As shown in Fig 3. the punch controllers 1.) are shortci chat thecontrollers 14, and the latter are formed with a lateral projection 46which projection passes through sl ts {i9 (Fig. 8) -when thecorresponding controller is raised. The notched selector hars arc so.arranged in the present apparatus that one'of the controllers .15 whichoperate the punches in making the lower row Of'1NII'l' UI'iIUUHS. isalways the last of the group. That is. as arranged thctapc feeds to theleft and the groups are read from left to right so that for any givengroup there will always be a projection 48 raised through onc of theslots 49 in the path of a nose 50 on level" -i().-- \Vhcn the nose .30contacts with the projection lo on the last one of the controllers 13 ofthe group, then the lever itl-fulcrums on that projection and thecg'intinucd forward movement of lever :3? moves the lower end oflever-40 to the left. and through that movement the pawl 44 isretracted. or moved to the right. and engages the tccth of wheel 47 whenthe former comes to rest. \Vhen the main operating lever 27 is movedforward. lever 37 startson its forward movement slightly in advance ofthe forward movementof the punch head. This slight time interval permitsthe'nose of lever 40 to reach its final position before a rack ii on thepunch head (Figs. 5 and S) reaches the end of its forward movement.

The continued forward movement of the punch head causes the rack 51 toengage the pointed end 40' of lever 40 to lock the lat- .ter in positionand to prevent its rebound. W hen solenoid 9.5 is denergized and thepunclrhead retracted, lever 40 is released from engagement with the rack51 and nose 30 strikes aspring stop 52 which forms a fulcrum for lever40, moving the lower end of said lever at its point of connection withlink 42 to the right, and the continued rearward movement of lever 37causes a forward movement of pawl 44 to feed the ratchet wheel 47 andthereby the feed wheel 46, until the pawl strikes a stop 53. A stop 54limits the forward movement of lever 37. By proper adjustment of thestops 53 and 54 and proportioning the parts described, the tape isalways fed an amount equal to the length of the group of perforationsand any additional amount desired to space the groups.

As shown in Fig. 8, I provide a stop 55 with which the nose of lever 40engages when the space bar of the key board is operated. From theforegoingdescription it will be seen that the farther the nose of lever40 is moved to the left, the less will be the feed of the tape. 7

As shown in Fig. 7 I attach a spring 56 to lever 4-0 to slightly retardthe lower endof lever 40 when it is moved forward and to insure that theupper end of said lever moved forward first. I also provide a back lashpawl 57 for ratchet wheel 47.

To insure positive engagement of the teeth of feed wheel 4.6 with thecenter row of perforations on the tape, I provide a toothed roller 58 onone end of a lever 59 pivoted at its centerv The teeth of roller 58 passbetween the teeth on the feed wheel 46 and force the paper over theteeth of the latter. The lever 59 carries at its other end a pressureroll 60 in proximity to stripper Lcvcr 59 is pivoted on aspring-pressedlever 62 to hold the rollers 58 and 60 to their work.

As before stated the bracket 20 is recessed, as shown in Fig. 5, toprovide a space for the passage of the tape back of the die 23. Toconfine the tape in this space I provide a cover 63 hinged to thebracket 20. VVhenthe tape is to be inserted the cover 63 is thrown back.the space provided for the tape is the width of the tape and .the,latter is therefore pre vented from shifting out of place, thus insuringthe proper alinement of the perforations. A chute til is provided (Fig.2) to receive the punches which fall in a suitable receptacle Q5.

In thepresent apparatus the roll of tape is supported on a reel 66 freelyrotatable on a stud carried by a bracket 67. Rig-idly secured to saidbracket is an arm 68 to which is pivoted, at its free end, a swingingarm 69. On the free end of said arm is a roll 70 around which the tapepasses from the reel to the perforator. Fixed to the arm 69 is a brakeshoe 71 adapted to bear against the periphery of wheel 66 and held innormal engagement therewith by a spring 72. The intermittent rapid feedof the tape draws the arm 69 and the brake shoe 61 away from the reeland as the latter is delicately poised, the tape is unwound until thereis slack in the tape when spring 72 causes the brake shoe to contactwith the reel, and stop its rotation and prevent an undue amount of tapebeing unwound'bctween the feeding movements.

As in my former application the selector mechanism is purely mechanicalin its construction and operation the punch selectors being operated bya system of levers. The only electrical means employed by me is thesolenoid :25, adapted to move forward the main operating lever 27. Theparts connected to and controlled by the movement of said lever arepurely mechanical in construction and operation. This elimination ofwiring systems, motors, clutches, etc., as heretofore employed, greatlysimplifies the construction of this class of apparatus and rendersunnecessary the employment of expert electricians to repair or put inorder.
